Examples of the following,

Referring to fig. 1 to 3, the present embodiment provides a rivet plug, which includes a stem 10 and a sleeve 20, wherein a break point groove 101 is formed on a stem of the stem 10, a head 102 is formed on one end of the stem 10, a diameter of the head 102 is larger than a diameter of the stem, and a stem between the head 102 and the break point groove is a head neck portion 106. The sleeve 20 is a hollow ring structure, the diameter of the annular inner hole of the sleeve 20 is larger than that of the rod body, and the diameter of the annular inner hole of the sleeve 20 is smaller than that of the nail head 102; the length of the stud neck portion 106 is less than or equal to the length of the sleeve 20.

When the rivet gun is used, as shown in fig. 3, when the rivet gun breaks the rivet rod 10 at the breakpoint groove 101, the rivet head 102 is extruded with the sleeve, so that the flange of the rivet head 102 is buckled on the end face of the sleeve, and the end face of the rod body at the breakpoint groove is propped against the rivet gun, so as to form a flange buckled on the other end face of the sleeve, so that the rivet head 102 and the rivet head neck part 106 are wrapped and sleeved in the sleeve, and the problem that the rivet head 102 and the rivet head neck part 106 fall off is effectively prevented. Meanwhile, the deformation of the sleeve per se pushes and contacts the hole to be sealed to form sealing, so that the effect of completely sealing the hole is achieved, and the problem that the nail head 102 and the nail head neck part 106 fall off cannot occur.

Specifically, as shown in fig. 3, the sleeve 20 is sleeved on the nail shaft 10 and placed in a hole for sealing and riveting, and then a rivet gun is used for riveting, wherein an annular arc surface bulge is arranged on the gun nozzle end surface of the rivet gun. Because the length of the head neck portion 106 is less than or equal to the length of the sleeve 20, in the case of less than, it is necessary to keep the head neck portion in cooperation with the annular arc protrusion for abutting, so as to achieve the purpose of flanging the head neck portion 106 after extrusion, as described in detail below.

During the operation of riveting sealing, the plane part of riveter rifle mouth can push up and support on the terminal surface of sleeve pipe 20, and the rifle mouth of riveter goes up the protruding terminal surface that can push up and support on the terminal surface of pin fin neck part 106 of annular cambered surface, then when through riveter pulling nail pole 10, the protruding terminal surface that can carry out the turn-ups to pin fin neck part 106 of riveter, then detain on the terminal surface of sleeve pipe 20, pin fin 102 supports each other with sleeve 20 simultaneously and supports and form the turn-ups to detain on the other terminal surface of sleeve pipe 20, reach and fix the purpose on the sleeve pipe with pin fin 102 and pin fin neck part 106, prevent that nail pole 10 in use from taking place the problem that breaks away from, improve leakproofness and structural stability.

And when the riveter pushes up the turn-ups to the nail pole, sleeve pipe 20 also can receive the axial extrusion of riveter, then sleeve pipe 20 carries out extrusion deformation or inflation packing in the axial, carries out inseparable cooperation to nail pole 10 and the hole of treating to seal fixedly. After the pulling deformation of the sleeve 20 and the shank 10 to the completion of the rivet seal, the shank 10 is pulled apart at the break point groove 101, leaving the head 102 and the head neck portion 106 inside the sleeve 20. Realized, it is fixed to carry out the cladding to nail pole 10, and it is sealed to fill this hole simultaneously, through the firm sealed cooperation of structure, improved the well sealed purpose to the hole.

In this embodiment, the annular groove 1021 is arranged on the end face of the nail head 102 facing the shaft, and due to the design of the annular groove 1021, the nail head 102 can be deformed more easily when being pushed against the flange, and meanwhile, the annular groove 1021 can also be matched with the deformed sleeve 20, so that the structural matching stability is improved.

As shown in fig. 2 and 3, the present embodiment is provided with a concave ring 103 on the shank between the breakpoint groove 101 and the nail head 102. When the sleeve 20 is compressed and deformed by the nail head 102, the deformed portion of the sleeve 20 is pressed into the concave ring 103 to form a fit, so that the effect of fixing the nail head 102 is further achieved, the sealing connection between the nail head 102 and the sleeve 20 is improved, and the structural stability after the rivet plug is sealed is improved.

As shown in FIG. 2, in this embodiment, the nail head 102 is a flat nail head 102, and the flat nail head 102 structure can conveniently design the matching dimension of the structure, and at the same time, can extrude the sleeve 20, and is easily buckled by the flanging button formed by the sleeve 20, and forms a seal.

As shown in FIG. 1, the other end of the shank 10 of this embodiment is provided with a tapered end 104, and the tapered end 104 facilitates entry of the shank 10 into the installed equipment for increased utility.

In the embodiment, the grooves 105 are formed in the shaft between the conical end 104 and the breakpoint groove 101 at equal intervals, and the design of the grooves 105 can reduce the shaft friction of the nail shaft 10 during riveting, reduce the abrasion of tools (such as a rivet gun) and improve the practicability.

The sleeve 20 is an aluminum sleeve 20 in this embodiment, and the aluminum sleeve 20 has good ductility, so that the sleeve 20 can be tightly matched with the nail shank 10, and meanwhile, the purpose of effectively sealing the hole can be achieved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
